PATENT .OFFlCE 2,180,518 DESK SET Carey Garfield Gregory, Los Angeles,Calif. Application June 10, 1938, Serial No. 213,056 8 Claims. (01.120-59) My invention relates broadly to desk sets and more particularlyto an improved construction of desk set operating upon the principle ofhydrostatic pressure for feeding ink to a dip pen well.

One of the objects of my invention-is to provide an improvedconstruction of hydrostatic desk set which facilitates quantityproduction at relatively low cost.

Another object of my invention is to provide a construction ofhydrostatic desk set formed from a minimum number of parts capable ofbeing molded from a variety of synthetic materials.

Another object of my invention is to provide a construction of moldabledesk set having a mini- 15 mum number of parts with the pen receivingguide formed integrally with the molded structure of the desk set.

A still further object of my invention is to provide a construction ofmolded desk set in which certain of the parts interfit with each othertelescopically forming an ink receiving receptacle into which a dip penis adapted to be submerged.

Still another object of my invention is to provide a construction ofdesk set operative upon the hydrostatic principle in which the quantityof the ink supply in the receptacle into which a dip pen is adapted tobe submerged is restricted in comparison with the quantity of inksupplied to the receptacle by the hydrostatic pressure.

30 Still another object of my invention is to provide a desk set havinga minimum number of interengaging parts and in which the line ofvdivision of the parts may be wholly obscured in the process ofmanufacture of the parts and a unitary 35 appearance imparted to thedesk set for improving the esthetic qualities thereof.

A still further object of my invention is to provide a construction ofmolded desk set in which a pressure equalizing aperture is molded 40directly into that part of the desk set which also unites integrallywith the pen receiving guide in the desk set.

Other and further objects of my invention reside in the improvedconstruction of molded desk set as set forth more fully in thespecification hereinafter following by reference to the accompanyingdrawings in which: v

The improved desk set of my invention is the result of extended researchand development in the art of desk sets operating upon the principle ofhydrostatic pressure of the class set forth in my Patents 2,026,529,granted January '7, 1936 and 2,112,907, granted April 5, 1938.

In my improved construction of hydrostatic 3 desk set, the parts arereduced in number by molding the principal parts integrally as a unitfrom synthetic moldable material. The pen re-' ceiving guide throughwhich a dip pen is adapted 0 to be inserted is molded integrally withthe top portion of the molded base structure. I have found that it iswholly unnecessary to construct the guide for the dip -pen independentlyof the base structure for in the improved arrangement of my inventionthe socket constituting the pen guide is integrally molded with theupper portion of the base structure. The pressure equalizing port ismolded directly into the upper portion of the base structure. Thecentral bore through which the threaded neck of the ink supply bottleextends isprovided with screw threads molded directly into the materialof the upper portion of the base and all bushings or threaded inserts orgaskets dispensed with in establishing connection between the ink supplybottle and the upper portion of the base.

The quantity of ink in the pool or reservoir into which the point of adip pen is adapted to be inserted. is restricted in the improvedconstruction of my invention so that a smaller quantity of ink isconsumed than in hydrostatic desk sets of previous constructions and thesmaller quantity of ink maintained in better writing condition than isthe case when a larger quantity of ink is maintained in the ink pool.The parts of the desk set are molded from synthetic material of variouskinds such as Resinox, Tenite, Porcelain, Bakelite and other phenolcondensation products. I may mold the parts of the desk set from glassor other transparent material. Two principal parts are required; thatis, the lower base portion which receives the ink supply and the upperbase portion which provides telescopic interengagenient with the lowerbase portion. In constructions where the division between the upper andlower portions of the base is substantially transverse, the exteriorcylindrical wall is treated with a fusible material which enters thetransverse division between the upper and lower portions of the base andafter being fused and baked, presents a substantially invisible seamwhich when coated presents an esthetic and ornamental appearance. Inarrangements where the upper and lower portions of the basetelescopically engage for substantially the entire depth of the base,the cemented joint is entirely invisible when the base is viewed in sideelevation. The restricted ink pool into which the dip pen may beinserted may be molded integrally with the lower portion of the base ormay be in the form of an eccentrically mounted receptacle confinedwithin the base. The principles of my invention may be carried out invarious embodiments and the forms set forth herein are to be consideredin the illustrative sense and not in the limiting sense.

Referring to the drawings in detail, reference character -I indicatesgenerally the base of the desk set of my invention comprising a lowerportion 2 and an upper portion 3 which are cemented together at theirinterengaging peripheries by suitable fusible material indicated at 4 inFigs. 2 and 5. The lower portion 2 of the base I is provided with arecessed reservoir 5 for containing the ink pool into which the dip penis adapted to be inserted. The upper peripheral edge of the recessedreservoir 5 is beveled as indicated at 6 which allows the angularlydisposed wall of the integrally molded pen receiving socket 6 to extenddownwardly into the recessed reservoir 5 without obstruction. Thelowerbase portion 2 is provided with an annular ledge l within thelimits of which. the recessed reservoir 5 is formed and above which theperipheral shoulder 8 on the lower portion 2 of the base projects. 7

The. upper portion of the base 3 is provided with an annular dependingwall 9 which telescopically engages within the peripheral shoulder 8 andextends toward the annular ledge 1. The upper portion 3 of the base isprovided with a central circular top 10 from which there depends acentral cylindrical portion H. The central cylindrical portion l l isrecessed as indicated at 12, the recess I 2 terminating in a shoulderl3. The internal bore of. the central depending cylindrical portion IIis screw threaded as indicated at M for receiving screw threads 23formed on the neck of the ink bottle 22 in the inverted positionillustrated in Fig. 2. The upper portion of the base 3 is provided withan inintegrally formed vent l5 serving as a pressure equalizing port inthe hydrostatic operation of the desk set. The dip pen receiving socketis formed integrally with the upper portion of the base 3 as representedat It. The pen receiving socket projects upwardly from the upper portion3 of the base as indicated at I! for receiving the dip pen which I haveshown generally at 26. The pen receiving socket It comprises theupwardly projecting integral portion H which is substantiallyfrusto-conical in shape, the cylindrical portion IS, the frusto-conicalportion 20, and the restricted cylindrically apertured portion 2!through'which'the pen point 3'!) of the dip pen is adapted to beprojected. The pen holder 26 has a peripheral extremity 27 thereon and arounded end portion 29 spaced. therefrom by means of the interposedcylindrical portion 28 of the pen holder. The rounded end portion 29 andthe peripheral extremity 27 of the pen holder coact to substantiallyclose the socket of the pen guide when the dip pen is in position asrepresented in Fig. 2. The pen receiving socket is thus substantiallyclosed at all times when the pen holder is not being carried in the handof the writer. Accordingly, dust and foreign matter are excluded fromthe pool of ink pressure is supplied to the pool of ink 31 from thesupply of ink in the bottle 22. A suitable protective and ornamentalcover is provided over the ink bottle 22. To facilitate the mounting ofthe desk set on a supporting surface, I

may provide adhesive pads shown generally at 32 In the manufacture ofthe desk set shown in Figs. 1-6, the lower portion of the base 2 istelescopically fitted about the annular depending wall 9 with thefusible material 4 therebetween.

The parts thus prepared are subjected to a fusing and baking operationwhich results in the fusing of a substantial joint between upper portion3 and lower portion 2 of the base. This joint is substantiallyinvisible. When the base is dipped or sprayed or otherwise coated withornamental glaze or pigment, the joint becomes wholly invisible and thebase appears as a single unitary member. A pleasing and estheticappearance is provided because a streamlined effect is obtained byornamenting the surface of the upwardly projecting integral wall ll ofthe pen receiving socket, which ornamented surface continues withoutinterruption throughout the entire cylindrical side wall of the base i.

In Figs. 7-10, I have illustrated a modified form of the desk set of myinvention in which the upper portion of the hollow molded base is formedfrom a molding illustrated at 39. The molding 39 has a downwardlydepending skirt 4!] which is strengthened in spaced angular positions byvertically extending ribs ll. The ribs 4| provide supports for embedded.tubular inserts 42 which are screw threaded for receiving extending ribs45.

screws 43 which pass through lower closure plate 44 forming the bottomof the desk set.

The hollow molded base 39 is strengthened transversely by means of thesubstantially radially The hollow molded base 39 is also provided withan eccentrically positioned annular recess 46 having a pair of dependingwall portions 41 projecting from beneath the base 39. An annular gasket48 is seated in the anvnular recess 46 and provides a seal for the upperperipheral edge 49 of the ink receptacle 56. The ink receptacle 50 isthus supported eccentrically within the hollow molded base 39 in aposition for supplying ink to the point of the dip pen 26 inserted intothe pen receiving socket I6 as delivered from the ink supply bottle 22through restricted aperture 24. In order that parts of the form of myinvention illustrated in Figs. 7-10 may be readily compared to thecorresponding parts shown in Figs. 1-6, I have applied primed referencecharacters to the corresponding parts. That is to say, integrally formedpen receiving socket is shown at I6 having upwardly projecting integral.wall II including frusto-conical shaped wall portion I8, cylindricalshaped wall portion I9, frusto-conical shaped wall portion 26', andaperture ZI' in the end of the pen receiving socket I 6. The pool of ink3I' is replenished hydrostatically from the ink supply'bottle 22 throughrestricted orifice 24 for supplying ink to the dip pen point 36. Thescrew threads 23 of ink bottle 22 are engaged with screw threads I4 inthe central depending cylindrical portion II in central recess l2, theperipheral flange 23a of the ink bottle resting against the shoulder I3.The pressure equalizing vent is molded in the base 39 as represented atI5. The adhesive supporting feet for mounting the desk set on asupporting base are indicated at 32.

The assembly of the desk set of the form illustrated in Figs. 7-10 isvery simple in that itis only necessary to locate the receptacle 50 inthe eccentric position with the peripheral edge 49 thereof seatedagainst gasket 48 and then apply closure 44 by means of screws 43 to theunderside of base 39, whereupon the assembly is complete. The relativelysmall quantity of ink in receptacle 56 insures the efficient operationof the desk set and conserves the inksupply, at the same time preventingdeterioration and evaporation of the ink.

In the form of my invention illustrated in Figs. 11-14, the upper andlower portions of the base are molded from synthetic material having asubstantially cylindrical contour forming a telescopic engagement andpresenting a pleasing external appearance. The upper portion of the basehas been designated at 33 having a depending cylindrical skirt 34. Thelower portion of the base is indicated at 35 having an upwardlyextending cylindrical Wall 36. The cylindrical wall 36 and skirt 34 areunited by a suitable cement or glue 31. The lower portion of the base isprovided with an integrally molded receptacle 38 which is eccentric withrespect tov the central axis of the lower portion of the base 35. Thisreceptacle 38 provides a container for a restricted pool of ink shown at3| which conserves ink consumption and protects the ink againstevaporation and deterioration. In order that the parts of the structureshown in Figs. 11-14 may be readily compared to the parts of thestructure shown in Figs. 1-6, I have represented corresponding parts inFigs. 11-14 by double primed reference characters. That is to say, theupper portion of base 33 is provided with central recess I2 whichcontains shoulder I3" and internal screw threads I4 for receiving thescrew threaded neck 23 of ink bottle 22. Correspondingly, the penreceiving socket which is molded integrally with the upper portion ofthe base 33 is indicated at I6"yfor receiving the dip pen 26. The penreceiving socket I6 includes integrally molded upwardly projectingwall-I1, frusto-conical shaped portion I8, cylindrical portion I9",frusto-conical shaped portion 20", and aperture 2|. The pen point 30 isinsertable through the aperture 2|" in the pen receiving socket I6". Thepressure equalizing port for the hydrostatic desk set is shown at I5 inthe upper portion of the desk set indicated at 33. The adhesivesupporting feet for the desk set illustrated in Figs. 11-14 areindicated at 32".

The assembly of the desk set constructed according to Figs. 11-14, isvery simple. as it is only necessary to telescopically engage the lowerportion of the desk set 36 with the upper portion of the desk set 33 andapply the cement or glue 3'! therebetween to effect a rigid assembly ofthe hydrostatic unit.

In all forms of my invention, the screw threaded end of the ink bottleis engaged in the screw threads molded into the upper portion of thebase structure to a position in which the flange on the ink bottle abutswith the shoulder on'the upper portion of the base structure. Thecylindrical cover member is then inserted over the ink bottle 22 and thehydrostatic desk set is ready for operation. Because of the relationshipof the pen receiving socket with respect to the pool of ink below therestricted orifice of the ink supply bottle, a continued supply of inkmay be depended upon into which the point of the dip pen is insertedfrom time to time during writing operations. The pressure equalizingport I5 insures a continuous supply of ink from the ink bottle to thepool beneath the restricted orifice 24 under control of hydrostaticpressure.

I have found the improvements of my invention highly practical andefficient in operation but I realize that modifications may be made andI intend no limitations on the invention except as may be imposed by thescope of the appended claims What I claim as new and desire to secure byLetters Patent of the United States is as follows:
